Load balancer stickiness is what the cloud administrator should configure to solve the issue of the application frequently asking the users to log in again even when the session timeout has not been reached for a highly available web application running within three containers behind a Layer 7 load balancer with a WAF inspecting all traffic. Load balancer stickiness is a feature that allows customers to maintain user sessions or connections with the same server or node that provides a service or function, such as a web application, database, etc., even when there are multiple servers or nodes behind a load balancer. Load balancer stickiness can solve the issue by providing benefits such as:
Consistency: Load balancer stickiness can provide consistency by ensuring that users receive the same service or function from the same server or node throughout their session or connection, without any changes or variations.
Performance: Load balancer stickiness can provide performance by reducing the latency or overhead of switching between different servers or nodes during a session or connection, which may cause delays or errors.
Security: Load balancer stickiness can provide security by preserving and protecting user authentication or authorization information on the same server or node during a session or connection, without exposing or transferring it to other servers or nodes.
